This review is from: TP-LINK TC-7610 DOCSIS 3.0 Cable Modem
Pros: - Works with CableOne (ISP) and CableOne Business, which tops out at 200Mbit service.
- Easy setup
- TP-Link is becoming known as a brand which represents "good but not expensive"
- Pays for itself in under a year compared to renting the modem!
Cons: - Extremely light weight plus narrow base means that it easily falls over when the attached cables have any tension or torsion.
- Limited to a bit under 340Mbit service. This is not a problem for most, but if your ISP has faster-than-350Mbit service, keep in mind that you cannot reach it with this unit. I could not test this unit at above 200Mb/s: This limit is based on the documented limits.
My ISP's highest-end package doesn't even come close to that.
Other Thoughts: I have many friends which rent their cable modems for $6-$20/month depending on the ISP. Even at the lower-end ($6per month), this unit will pay for itself in less than a year, even considering time value of money. Typically, a purchase is considered a good investment if it makes back its cost in 3 years or less, so it makes absolutely no sense to continue renting unless your rental fee is extremely low (under $1.50/month).READ FULL REVIEW
Pros: I reviewed one of these (the 12TB version, though the only difference is the space available) as an EggXpert and since got another one and recommend them to my friends and colleagues.
This my favorite NAS of all time, though I also really like Synology or NetApp when money is no object (See Other Thoughts for business features).
The WD MyCloud is much more than just a networked set of hard drives. Here are a few of the cool things it can do:
- Auto-update its own firmware, so you don't need to deal with it. The firmware seems so well designed, I trust WD to get this right, and they do.
- Turn itself off to save power at night (or on whatever shedule you want)
- Use 2 network connections in case one fails (link aggregation). Note: In certain cases this could improve performance too, but probably not with only two hard drives.
- Monitor a battery backup (UPS) and tell other computers to shut down safely when the battery is low.
- Send an email or SMS message if a problem occurs (like disk full or if a drive fails)
- Auto-backup your computers, camera, or USB drive.
- Graphically monitor usage and network activity
- Supports not just RAID1 and 0 but also spanning and apparently a "separate drives managed separately" option that they call JBOD.
The distinguishing characteristic, however, is how easy and clean WD made the user interface. It so so simple and intuitive to get things done. I wish I could share screen captures to show you what I mean.
Cons: The firmware incorrectly presents JBOD as "The use of one or more drives not in a RAID configuration but managed as separate logical volumes." and spanning as "Combination of drives in a linear fashion to create one large logical volume."
In every context I have ever seen, JBOD and spanning are the same thing. JBOD arrays are not presented as individual drives, despite the acronym.
Other Thoughts: The EX2100 is one of the higher-end WD NAS units and as such has a number of features useful to businesses:
- Microsoft ActiveDirectory authentication
- Advanced link aggregation/trunking (AKA teaming, bonding, etc.) including load balancing, 802.3ad, and others.
- LLTD (quality of service diagnostics and network topology)
- Share aggregation (Show shares from several NAS units as one)
- Max SMB version settings (limit to SMB 1, 2, or 3)
- Configurable NTP (time server)
- One WD NAS can backup another WD NAS in a remote location
- SSH server, NFS server, WebDAV, and FTP.
I can set one of these up and have it usefully on the network in about 6-8 minutes.
Pros: As an engineer at a major semiconductor manufacturer, I was in an unusually good position to test this power supply's quality in detail.
A key mark of a good power supply is steady voltage as load changes.
We measured power with a very advanced oscilloscope capable of 5x the bandwidth required by the ATX specification and calibrated just 2 weeks earlier.
For each voltage, we took 2500 samples using a running PC as a real-world load. We ran a low load since many power supplies have a hard time not going over voltage specs.
Short version: The power supply design is very good. *Every* sample was within within +/- 5% of the base voltage. There wasn't a single spike in over 17,000 measurements!
See "Other thoughts" for more detailed data.
During the test, the power supply was cool to the touch and entirely silent the whole time. The fan never turned on because it wasn't needed.
During an informal test on my own system -- a 6-core DDR4 machine overclocked to 4.3GHz, the fan activated at load but was too quiet to hear from 3ft away. I can use this to replace my fanless Rosewill Silent Night without increasing system noise significantly.
Cons: Being a fully modular power supply (even the 24 pin motherboard connector, odd as that seems), the fit inside some cases is a little tight,. The plastic connectors stick out more than 1/2" past the power supply. In a cramped space, assume at least 1" of room past the power supply is needed when you add cable bend.
As with many high-end power supplies, this one ships with a fancy velvet carrying case. How often do you carry your power supply around at a party? It seems a silly trend and I hope it adds no more than 2 cents to the unit's cost.
Other Thoughts: +3.4v:
Standard Deviation: 0.024329617
Max Voltage: 3.44
Min Voltage: 3.3
Standard Deviation: 0.029969411
Max Voltage: 5.24
Min Voltage: 5
-12v (note that ATX allows +/- 10%, but this unit was still within 5%):
Standard Deviation: 0.057962843
Max Voltage: -12.16
Min Voltage: -12.56
Standard Deviation: 0.033915673
Max Voltage: 12.48
Min Voltage: 12.16
Difference from ground (FYI):
Standard Deviation: 0.018717451
Max Voltage: 0.112
Min Voltage: -0.088
Full data and oscilloscope screen captures available upon request.
I can run a full analysis in JMP, but as you can see the voltage is very stable across all voltages.
